The line l is vertical and parallel to the y-axis. Since the horizontal run (x₂ – x₁) between any two points is zero, division by zero makes the slope undefined.

Ganita Manjari Part 2 chapter 13 Two Variables, One Line solutions
The line l is a vertical line parallel to the y-axis, located at x = -2. For any two points selected on this line, the x-coordinate does not change, resulting in a horizontal run of zero. Since calculating the slope requires dividing the vertical rise by the horizontal run, division by zero occurs, which means the slope is completely undefined.
